Benefits of technology

[0010]This enables network capacity to be increased and more effectively used. Since content can be delivered faster than with previously proposed schemes, it also enables resources to be released earlier.
[0023]The delivery server may increase the bandwidth to the maximum bandwidth available, so as to provide a burst delivery rate which is as high as the network will permit. Alternatively, the delivery server may increase the bandwidth gradually.

Problems solved by technology

Moreover, networks may have additional resources which are unreserved for short periods of time, eg during periods of low network demand.

Embodiment Construction

[0037]Referring to FIG. 1, there is shown a network arrangement operating in accordance with the present invention. A UE 1, in this case an IPTV UE (set-top box plus display for example) is connected to the network to receive data from the network. The UE 1 is provided with associated storage, such as solid state memory, a hard disk drive or similar, so that data received from the network may be stored locally on the UE 1. This may be integral, or connected locally, by a hard link, wirelessly or otherwise associated with the UE. Whilst only a single UE 1 is shown it should be appreciated that there will generally be a large number of UEs 1 connected to the network, with network resources shared between the UEs 1.

[0038]The network is a NGN (next generation network), ie a network designed using IP and QoS (Quality of Service) technology to support all types of customer traffic including but not limited to voice, data and video, which enables a variety of IP-based customer devices and ...

Abstract

A multimedia delivery network, comprising network resource allocation means for allocating bandwidth to a network session between a UE (user equipment) device on the network and a delivery server, wherein the allocation means is adapted to reserve a nominal bandwidth for the network session when the session is opened, which permits delivery of data from the delivery server to the UE at a nominal service rate, and wherein the delivery server is adapted to increase the bandwidth of the session, to a higher bandwidth once the session has been opened, so as to permit delivery of data from the delivery server to the UE at a burst delivery rate higher than the nominal rate.

Description

BACKGROUND OF THE INVENTION[0001]This invention relates to the optimisation of bandwidth utilisation in delivery networks. In particular, it relates to a multimedia delivery network in which the network resources reserved for a network session may be varied in accordance with available network resources. The invention may be applicable to on-demand multimedia delivery, gaming, content sharing or other services requiring Quality of Service (QoS).DESCRIPTION OF THE PRIOR ART[0002]In order to provide competitive service quality, to retain existing customers and to appeal to new customers, IPTV (Internet Protocol TV) and increasingly OTT (over the top) service providers rely on the QoS (quality of service), provided by delivery networks, to deliver multimedia content and services. Examples of such services include IPTV video on demand, video from Internet video-sharing sites, and broadcast TV, all of which may be delivered over Internet Protocol (IP) networks. The quality of service (Qo...
